Eddie Murphy

Eddie Murphy's performance in 2006's Dreamgirls as soul singer James Early was easily his most challenging dramatic role to date. It also earned him the first serious awards attention of his lengthy career; he racked up a Golden Globe and was also nominated for an Oscar for the film. Murphy hasn't followed up with a similarly serious movie yet, but Dreamgirls stands as proof that he can pull off a dramatic turn.Source: NBC and Dreamworks Pictures
